Philip,
I agree the likelyhood of the motor mounts being defective is minimal, but these things (and others) are mass produced, so it is conceivable that things can be bad. Since the time and effort to replace 1 of the mounts might be an issue, they suggested to replace all 4.
To give you an example of production issues, my 2002 Camry LE V6 had a malfunctioning shift solonoid and required a transmission service at about
8,000 KM or 5,000 miles. Yes this is a very rare occurrence, if not a fluke, but mistakes do happen regardless of who the manufacture is.
